Going Green: Your own easy to install rainwater catchment system
So you want to save the world one drop of rain at a time while also saving on your monthly expenses? Then you sure have come to the right place! Water collection systems are a fun weekend project for the family that are fairly easy to do. You can make it as simple as a rain barrel at the bottom of your gutter system or as sophisticated as a buried underground tank with multiple filtration and pump systems.
You can't escape gravity
Use gravity to your advantage for once and collect the water that comes off your roof every time it rains. The bigger the roof the better this works! The first thing you are going to need here is a collection basin or a tank. This can be made out of any material capable of holding water such as wood, plastic, metal, or concrete. This is your time to shine so get creative here. Unless you bury it this is going to be a very visible part of your backyard so it should be as ascetically pleasing as possible. You can enjoy yourself here; try having the kids paint it to liven up the gardens "feng shui". If you plan on using it during the cold weather make sure it is properly insulated or buried more then 4 feet underground.
The bigger it is the more water you can hold
Basically Carried Everywhere!
The math is simple, you can collect over a half gallon of water per inch of rain fall for every square foot of roof that you have. Add it up because that is a lot of water even for folks with smaller roofs!
For most people just run an extension from the gutter downspout directly into the tank. The tank can have a release valve at the bottom to drain or you can even utilize a pump for this purpose. If you use a pump you can get creative as gravity wont be a necessity anymore.
Rainwater can get a little dirty over time so make sure you clean out your collection basin periodically. A best practice is to completely drain it at least once a year and clean it thoroughly with bleach or another antibacterial soap to prevent algae growth.
Keep a close eye on the tank to make sure the winter hasn’t caused any cracking or other damage. make sure everything is properly secured and wont tip over when it gets full with water. If at all possible, keep the tank covered to prevent bird droppings or insects from getting into it. Needless to say this water is best used for gardening or other similar purposed NOT TO DRINK.
As you get more advanced you can add a filtration system to the array. Depending on the quality it will allow you to use your newly acquired water for a variety of purposes. Rain water tends to be a little more acidic so make sure and test the PH if needed.
Another fun project is to create an aquaponics system and use the rainwater to run it.Check out this link to read further about the endeavor.
